VerifyHostKeyDNS not working, fix does exist in version 246

Asked by Daniel von Obernitz


in Ubuntu 20.04 there is a bug concerning VerfiyHostKeyDNS, that prevents automatic key validation.
The bug is already reported and solved by the systemd developers.

but only for version 246. Ubuntu 20.04 still uses 245. Will there be an update to 246 soon?

Best regards

You cannot expect that Ubuntu will upgrade a critical system function like systemd from 245 to 246 in an already-published LTS release.
Standard procedure would be to cherrypick the related patch and apply it to the current version.

I suggest that you create a bug report, specifying what's wrong in the current version, and which change has to be applied to correct it. See the SRU template (follow the links in the FAQ).

Thanks for your answer...
I didn't expect anything, I was just asking for a way to solve this issue, especially for an LTS version.

But since there won't be version changes as you described I will create a bug report for the related patch.
